Diarrhea is a major health problem especially for children under the age of 5 and up to 17% of children admitted in the pediatric ward die of diarrhea. A range of medicinal plants with anti-diarrheal properties is widely used by traditional healers.


The ethyl acetate extract of Pedalium murex L., (250, 500, and 1000 mg/kg body weight) was administered orally to three groups of rats (five animals per group) in order to evaluate the activity of the extract against castor oil-induced diarrhea model in rat. Two other groups received normal saline (5mg/kg) and loperamide (5mg/kg) as positive control. The effect of the extract on intestinal transit and castor oil-induced intestinal fluid accumulation (enteropooling) was assessed.


At oral doses of 250, 500, and 1000 mg/kg body weight, the plant extract showed pronounced and dose-dependent anti-diarrheal activity. The protective role of the extract at 1000 mg/kg was comparable to that of the reference drug, loperamide (5mg/kg). The extract (1000 mg/kg) produced a decrease in intestinal transit comparable to atropine (5mg/kg), and significantly (p<0.01) inhibited castor oil-induced enteropooling. No mortality and visible signs of general weakness were observed in the rats following the extract administration of up to a dose of 6000 mg/kg.


The results showed that the extract of Pedalium murex L., has a significant anti-diarrheal activity which supports its use in traditional herbal medicine practice.
